IMPROVEMENT IN CORN-PLANTERS.

lSpecification forming part of Letters Patent No. 28,847, dated .lune2G, 1860.

To all whom it may concern:

Be it known that I, DAvIs DUTCHER, of Blue Grass, inthe county of Scottand State of Iowa, have invented certain new and useful Improvements inCorn-Planting Machines; and I do hereby declare the following to be afull, clear, and exact description of the construction and operation ofthe same, reference being had to the accompanying drawings, making apart of this specication, in which-A Figure l represents a perspectiveview of the machine. Figs. 2, ,8, and 4 represent transverse sectionsthrough the same at different points. Fig 5 represents atop plan, andFig. 6 represents a side elevation ofthe machine.

Similar `letters of reference, where they occur in the several figures,denote like parts of the machine in all of them.

To enable others skilled in the art to Inake and use my invention, Iwill proceedto describe the same with reference to the drawings.

F represents a rectangular frame supported nea its rear by two wheels, CC, said wheels C C being fast on their axles D D', respectively, so lasto turn together.

O is the conductors or driver-s seat. placed rather behind the axles ofthe bearingwheels, so as to balance the machine and put it more underthe' control of the conductor.

Near the front of the frame F, and between the timbers, are twosupporting-pieces, a (l,

'furnished each with two slots, b c. Through the slots b bolts d pass,so that the supporting pieces freely move up and down on them. Throughthe lower slots, C, the axle or journals c pass, said axle carrying thetwo front supporting-wheels, ff. A bolt, Z, having a ringhead, m, bywhich it is suspended to the journals of said axle,passes through aflange, a, on the upper ends of the shoes or plows g, and by means ofthe nuts o o on the screw-bolt the plows can be raised or lowered on thesup porting-pieces or stocks a a.

B B are the hoppers, arranged one on each side of the frame, and R theseed tubes or ducts leading therefrom to the fnrrows opened `4by theshoes or plows g g. Shafts A A extend through these hoppers,which closeup the bottoms thereof, these shafts being furnished with recesses, asseen in Fig. 5, which receive the charge of grain, and as the shaftsrock or roll carry said charges of grain out of the hopper It is anddrop them into the seed-tubes, whence they drop into the furrows openedby the plows.

On the axle D of the main wheel C there yis a cogged wheel, E, whichgears with and turns a smaller cog-wheel, r, on the shaft D p, and thusturning said shaft. On each end ofthe shaft D p there is a crank, q (j,which, by means of its respective connecting-rod z, unites it with acrank, XV, on the seeding roller or shaft A, so that the continuousrotation of the shaft D p shall give a rocking Inotion to theseedingrollers A. There is also a hand-wheel, t,`on the shaftD p, whichthe driver or conductor from his seat O can grasp, so that if thedropping is in advance'or rear of the marks he may suspend or advancethe action of the seedrolls to make them correspond, or so that when thenecessity arises the dropping may be done by hand instead ofautomatically. The box, which carries that end of the shaft D p thathasupon it the gear-whecl 1', is secured to the frame by screws X, passingthrough slots w, .and tothe box is attached one end of a link or rod, Q,the other end thereof being attached to the short arm of a lever, F,pivoted at M, and extending up into convenient position for the driverto grasp, who, by forcing forward said lever, slides the cog-wheel r outof gear with.

Vthe Inain cog-wheel E, and thus throws out of gear the droppingapparatus as well. as the marking apparatus. v

On the cranks q q (or rather 011 their wristpins) are hung the markersyy, said markers being connected near their lower ends by a cross-brace,X, to which a hinged adj listing-bar, Y, is connected, said bar having aseries of ad- ]'usting-holes in it, l 2 3 4, Figs. l, 5, for regulatingor spacing the steps or marks'made by:

said markers as they rise, and are carried forward and droppedA by thecranks q g, to which they are hung, and thus marking the ground inadvance for the subsequent droppings, or making marks for guiding ordirecting the dropping, and for keeping it in check-rows for theconvenience of plowing or cultivating afterward.

A bar or shaft (marked C Gr) extends across the front part of themachine, to which a lever, II, is connected, and which extends backtoward the drivers Seat, where it passes through .or in contact with aguide or post furnished with a series of holes, (two or 1nore,) so thatby means of a pin said lever may be attached to said guide or post, fora purpose to be pres ently described'.

To the shaft C G are connected two arms or levers, H', to which the axlee is suspended by chains I, or other flexible connection,that will allowthe wheels f and plows y to rise at any time to pass interveningobstacles, and at the saine time allow the driver in his seat to raisethem up also whenever it becomes necessary to do so. The axle c isfurther braced and supported to and by the main frame through the rodsK, which extend back to and are secured on the rear cross-piece of theframe.

S are braces for holding` and adjusting the seed-tubes R in properposition with-regardto the shoes or plows. The rear wheels, C C, rollover the hills of corn thus planted and press down the earth upon thehills. The tongue is a rigid one. rEhe wheels f are regulators fordefining the extent to which the plows shall enter the ground.

Having thus fully described the nature and object of my invention, whatl claim therein as new, and desire to secure by Letters Patent,

l.. The combination ofthe seeding and marking apparatus, operatingtogether in the inanner and for the purpose substantially as described.

2. The combination of the plows and supporting and gaging wheels f, sothat they may DAVIS DUTCHER.
